ldeal for anyone with a trailer in tow, the NorCross Trailer Alert SP employs ultrasonic scanning technology to detect objects that you can't see while backing up. As a result, you don't have to worry about reversing your RV, trailer, or other big rig into a car, fire hydrant, picnic table, or--worst of all--a pedestrian. Easy to install and use, this device can help you prevent an accident. Simply attach the display's power wire to your vehicle's reverse light circuit, then connect the backup sensors and transmitter to your trailer's brown wiring. 0nce installed, the unit creates a six-foot radar field behind your vehicle with its two waterproof ultrasonic sensors, each of which includes a 10-foot harness.

When your vehicle approaches an object in the field, the unit's seven stage-coded LED indicators signal your distance to the object, while an audible alarm starts increasing in intensity the closer you get. There's no easier way to prevent thousands of dollars in damage and a headache-inducing conversation with the insurance company.

The Trailer Alert SP comes with a surface-mount LED display that attaches to your dash, along with two ultrasonic sensors and a waterproof transmitter with a 75-foot range. ln addition, it installs wirelessly on any trailer, including cargo, horse, commercial, and boat trailers, along with RVs and ATVs. This waterproof, impact-resistant system is backed by a two year warranty.
